UNIVERSAL COMPRESSION STOP AND WASTE COCK.

STEECIFICATION forming part of Letters Patent No. 751,869, datedFebruary 9, 1904.

Application filed June 11, 1903,

To all whom it may concern:

Be it known that 1, WILLIAM G. NEWTON, or New Haven, in-the county ofNew Haven and State of Connecticut, have invented a new and usefulIIHPIOVGIIXGIH] in Universal Compression Stop andWaste Cocks; andldohereby declare the following, when taken in connection with theaccompanying drawing and the numerals of reference marked thereon, to bea full, clear, and exact description of'the same, and which said drawingconstitutes part of this specification and represents a view in verticalsection of my improved cock shown closed to the entranceof'service-water'and open to the dischargeqof waste water.

My invention relates versal compression stop and waste cock, the objectbeing to produce a simple, convenient,

effective, and reliable device which is constructed with particularreference to simplicity and durability.

lVith these ends in view my invention consists in acompression stop andwaste cock having certain details of construction and combi- 2 5 nationsof parts, as will be hereinafter de-Z scribed, and pointed out in theclaim.

in carrying out. my invention as erein shown I employ a body 2 havingits inlet and outlet ends 3 and 3 'provided with internal threads forthe reception of the threaded ends of the service-pipes (not shown) ofthe servicewater system in which the cock is interposed. The said bodyis lso formed with an externally-threaded neck 4, located at a rightangle to the said ends 3 and 3 and having its inner edge beveled to forman annular bearing-sun face 5 for the reception of acorrespondinglybeveled annular bearing-surface'fi, forming the innerpart of a shoulder 7, made integral 4 with and encircling a rotatablechambered head 8. The square outer edge of the said shoulder 7 isengaged by the inwardly-extends ing flange 9 of a union 10, which isinternally threaded for being screwed upon the esternally-t ireadedouter end of t e neck 4. The said union 10 draws the beveled surfaces 5and 3 together, these surfaces being fitted to form what is known as aground-jointfl- "in setto an I improved uni-.

Serial No. 160,986. (No model.)

1 ting the cock to be usedin diflerent situations the chambered head 8maybeturned in the body 2 so as' to occupy any desired relation thereto.Then when it has been set as desired the union 10 is-screwed downto'bring 'the beveled surfaces 5 and tact. This capacity for adjustmentgives the 'cock its so-called universal. character. It will be perceivedthat in my improved cock no packings are necessary for this adjustment.The said body 2 is formed with a winding partition or web 11, whichentirely separates its inlet end 3 from its outlet end 3, except for awater-port 12, formed through the'said partition 11, the outer surfaceof which is, formed with a slightly raised horizontally arrangedvalve-seat 13, forming the stop-valve seat of the cock and arrangedconcentric with the said water-port 12. This valve-seat 13 coacts withthe washer-like stop-valve packing 14. The stop-valve packing 14 islocated entirely within a cup-like casing 15, which is internallythreaded to adapt it to be applied to the threaded stud 16, formed atthe inner end of the spindle 17, which is furnished at a handle 18. Thesaid casing 15 is formed at its outer end with a hub 19 the end of whichengages with the squared inner face of a shoulder 20, formed upon thespindle at the base of the stud 16 thereof. Between the flat outer faceof the casing 15 and the shoulder 20 of the spindle 17 I interpose aflat washer-like waste-valve packing 21, which coacts when the cock isopen with the waste-valve seat 22, which is located at or near thebottom of a circular shut-oil chamber 23, formed within the inner end ofthe head 8. It will be observed that the pack ing 21 is just a triflelarger in diameter than the casing 15, which does not make any contactwith the wall of the shut-oil chamber 23.

her 23 is slightly beveled, so as to act as a guide for the packing 21when the same enters the chamber, at which time the service-water isentirely or nearly cut off from thewaste: pipe 27. If the packing 21fits very closely within the shut-oil chamber, the service-water l wiilbe completelv The inner edge of the lower end of the cham- 6 into closeconits outer end with '95 (mt oil from the waste-pipe from the beginningof the opening of the cock up to the time of the seating of the packing21 upon the seat 22 in the bottom of the shutoff chamber; but in anyevent the packing 21 will fit the shut-oil chamber so closely that theamount of water which escapes, if any, through the waste-pipe during theoperation of the opening of the cock will be very inconsiderable. TheWaste-valve packing 21, the cup-like casing 15, and the stop-valvepackin 14 are all firmly held in place upon the threaded stud 16 bymeans of a nut 25 hearing against the lower face of the packing 14 andscrewed upon the outer end of the threaded stud- 16. The said shut-ofi'chamber 23 is connected with the waste-chamber 24 by a large circularpassage 26, formed in the head 8, which is provided with a waste-pipe27, leading directly out of the outer end of the wastechamber. It is toprovide for pointing this waste-pipe 27 in any desired direction thatthe cock is made with its so-called universal feature.

The spindle 20 is furnished about midway of its length with a heavycompression screwthread 28, which takes into a corresponding thread 29,formed within the outer end of the head 8, the said compressionscrew-threads 28 and 29 being located virtually above the path taken bythe waste or service water in its passage through the waste-chamber 24of the cock. At its outer end the chambered head 8 is externallythreaded for the reception of a s'tufiing-box cap 30, containing apacking-washer 31, which is prevented from entering the outer end of thethread 29 by a fender in the form of a metal guard-ring 32, set into arecess 33, formed within theextreme outer end of the chambered head 8.

When my improved cock is closed, as shown by the drawing, its spindle isturned inward and downward, so as to force its stop-valve packing 14firmly upon its stop-valve seat 13, whereby the direct passage ofanywater from the inlet service-pipe through the body 2 into the house orsystem is cut ofi. At this time, however, any waste water from the housemay enter the outlet end of the body and flow inward and upward over thepacking 21 and through the shut-off chamber 23 and passage 26 into thewaste-chamber 24 and out through the waste-pipe 27. To open the cock forthe inlet of service-water, the spindle is turned outward, with theeffect that almost imme diately after the packing 14 lifts away from theseat 13 the packing 21 enters the shut-ofl chamber 23, so that theentrance of water into the chamber 24 is entirely or substantially cutofi' prior to being completely out off by the forcing of the packing24against the seat22, which, so to speak, closes the waste.

I particularly wish to point out that when the cock is tully open thepacking 22, the casing 15, and the packing 14 are all Virtually has beenremoved from the body as described,

the stop-valve packing .14 and the waste-valve packing 21 are fullyexposed and may be replaced, if desired, without in any way dis.-turbing the spindle 17 or, indeed, by doing anything more than to removethe nut 25 and the casing 15. This provision of ready access to thepackings without disturbing any part of the valve is a point of greatconvenience. v

It is apparent that in carrying out my invention some-changes in theconstruction herein shown and described may be made; I would thereforehave it understood that I do not limit myself to the exact constructionshown, but hold myself at liberty to make such departures'therefrom asfairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a compression stop and waste cook, the combination with a bodycontainin a valveseat and furnished with an external -threaded neckhaving its inner edge beveled toform an annular bearing-surface, of a.chambered head having a circumferential shouldcrformed with a beveledbearing-surface meeting with the bearing-surface before mentioned 11)form a ground-joint, and the said head being formed at its extreme innerend with ashut-ofi chamher, with a valve-seat located at the bottom ofthe said shut-oi! chamber, with a waste-chamber, and with a pasmgeleading from thesaid valve-seat to the said waste-chamber; a wastepipeleading out ofthe said waste-chamber, a, spindle mounted in the outerend of the said chambered head, a stopvalve packing carried by thespindle and ooacting with the valveseat in the said body, a wastevalye pcking carried by the spindle and coacting' with the side walls of theshutofl chamber and with the valve-seat at the bottom thereof, and aunion-nut applied to the neck of the body and coacting with the shoulderof the chambered 7 head for drawing the said two beveledbearing-surfaces into contact, whereby when the cock is open thepackings are located within and protected by the shut-ofl chamber.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

WILLIAM G. NEWTON.
